How much of Angels & Demons are actually true?

I haven't read the book but I already watch the movie. I consider the movie as entertainment and haven't take it seriously that it can actually happen. I maybe consider as on looker only and really don't have an opinion on it. I really hope that there is real killing happening in the Vatican. lol.

the illuminati cult is true. the brands are also true. dark matter and genesis is also true science fiction is truly fiction.

All that is told and 'correctly' interpreted in the Bible about angels and demons is the truth. And not something that is told by a writer who want to make big money by selling his imaginations as the truth.
